ClearIsolation, Screening and Characterization of Plastic-Degrading Bacteria From Soil for PWM
Scientists isolated bacteria from soil near garbage sites and identified strains capable of degrading plastic materials, with scanning electron microscopy revealing physical damage — holes and cracks — to plastic surfaces after bacterial exposure within 30 days. The study contributes to the search for soil microbes that could be harnessed for biological plastic waste management. Biodegradation by indigenous soil bacteria could offer a more environmentally friendly alternative to landfilling or incineration of plastic waste.
Breaking down microplastics: insights into the role of actinomycetes in biotic degradation pathways
This review examines the role of actinomycetes — soil bacteria known for antibiotic production — in biodegradation of microplastics, identifying species with enzymatic degradation activity and discussing their potential for bioremediation applications.
Enrichment and isolation of micro plastic degrading microorganisms from various natural sources
Researchers isolated microplastic-degrading microorganisms from soil and water samples using mineral salt media with polyethylene and polypropylene as sole carbon sources, successfully identifying four distinct microbial isolates capable of degrading these polymers.
Biodegradation of Low Density Polyethylene (LDPE) using marine bacteria isolated from tropical beaches of megacity Mumbai
Marine bacteria isolated from plastic debris buried in beach sediments at seven Mumbai beaches were able to colonize and partially degrade low-density polyethylene (LDPE) plastic. Identifying bacteria naturally adapted to plastic-rich marine environments is a step toward developing biological tools for plastic degradation, though the process is currently far too slow to address the scale of ocean plastic pollution without significant enhancement.

Isolation of a soil bacterium for remediation of polyurethane and low-density polyethylene: a promising tool towards sustainable cleanup of the environment.
A soil bacterium tentatively classified in the Pseudomonas genus was found to biodegrade both polyurethane and low-density polyethylene plastics. The discovery of a single bacterial strain capable of degrading two different types of plastic is a step toward developing practical microbial tools for plastic waste remediation.
